Apple has made the fifth developer beta versions of High Sierra 10.13.4, iOS 11.3, and tvOS 11.3 available for download by testers, just one week after the company shipped the fourth betas of each operating system.

The first beta of iOS 11.3 is now available, giving developers the opportunity to build apps for ARKit 1.5, and to test out new features like Health Records and new Animoji. However, new settings for battery and performance controls will have to wait until later betas.

One week after the last batch, registered members of Apple's developer program can now access the fourth pre-release beta builds of operating systems for the iPhone, iPad, Mac, Apple TV, and Apple Watch.
